FIELD: metal processing.
SUBSTANCE: invention relates to metal forming, in particular, to forming parts. Press comprises at least two press tools, at least one slide and at least one hydraulic drive of slider. Drive is equipped with at least one working element, which moves in working chamber with working fluid. Working element separates from each other first and second sub-chambers. In press there is at least one device for measuring coordinates of slider during working stroke. To feed working fluid into working chamber, press is equipped with at least one reservoir, at least one first hydraulic feed device and at least one second hydraulic feed device. First sub-chamber and reservoir are connected with at least one controlled hydraulic valve. There is a control device, that is connected a device for measuring coordinates of slider, with first and second hydraulic feed devices and with controlled hydraulic valve.
EFFECT: enabling installation of press stroke and elimination of overload.
